Scenario Overview
Port and coastal environments subject optical cables to extreme conditions: salt spray corrosion, high humidity, UV radiation, and mechanical stress from marine operations. Standard outdoor cables degrade rapidly in these conditions.
The primary protection strategy combines corrosion-resistant PE sheath materials, enhanced water-blocking structures, and UV-stabilized outer jackets to achieve 20+ year service life in marine environments.
Primary Protection Strategy
Double-layer PE sheath with anti-corrosion additives, combined with full water-blocking gel or dry water-blocking tape, provides comprehensive protection against salt spray and humidity.
